Ich bin neu in Kivy. Ich möchte eine App erstellen, die Benutzertexteingabe nimmt, und sie dann anzeigen. Aber wenn die Benutzereingabe sehr lang ist, möchte ich, dass der Anzeigebereich scrollbar ist.Wie Sie Scroll-Widget in Kivy hinzufügen?
Ich habe einige Tutorials gemacht und kann beide Dinge getrennt machen, aber ich habe Probleme, sie zusammen zu setzen.
Hier ist der Code scrollbaren Text zu ermöglichen:
__version__ = '1.0.1'
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.uix.widget import Widget
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.uix.scrollview import ScrollView
import warnings
import string
from kivy.base import runTouchApp
from kivy.lang import Builder
from kivy.properties import StringProperty
Builder.load_string('''
<ScrolllabelLabel>:
Label:
text: root.text
font_size: 50
text_size: self.width, None
size_hint_y: None
height: self.texture_size[1]
''')
class ScrolllabelLabel(ScrollView):
text = StringProperty('srgsdrgsdfh dsfg dvgf vgsdfv srfvsdfsdrfv sevrv sdrfv serv serv serv servsrd vsv srvsdrfvvv' * 10)
runTouchApp(ScrolllabelLabel())
Und hier ist der Code angezeigt werden, was Sie eingeben:
__version__ = '1.0.1'
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
from kivy.uix.widget import Widget
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.uix.scrollview import ScrollView
import warnings
import string
from kivy.base import runTouchApp
from kivy.lang import Builder
from kivy.properties import StringProperty
class SomeApp(App):
def build(self):
grid = GridLayout(cols=1, size_hint_x=None, width="600dp")
self.lbl0 = Label(text='Tap and type a word/phrase below') # create a label instance
grid.add_widget(self.lbl0) # physically add the label onto the layout
self.txt1 = TextInput(text='', multiline=False) # create a text input instance
grid.add_widget(self.txt1) # physically add the text input onto the layout
self.lbl1 = Label(text='Display') # create a label instance
grid.add_widget(self.lbl1) # physically add the label onto the layout
btn1 = Button(text='Press') # create a button instance
btn1.bind(on_press=self.mirror) # binding the button with the function below
grid.add_widget(btn1)
return grid
def mirror(self, userInput):
self.lbl1.text = self.txt1.text
SomeApp().run()
Aber ich kann sie nicht kombinieren:
__version__ = '1.0.1'
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
from kivy.uix.widget import Widget
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.uix.scrollview import ScrollView
import warnings
import string
from kivy.base import runTouchApp
from kivy.lang import Builder
from kivy.properties import StringProperty
Builder.load_string('''
<ScrolllabelLabel>:
Label:
text: root.text
font_size: 50
text_size: self.width, None
size_hint_y: None
height: self.texture_size[1]
''')
class ScrolllabelLabel(ScrollView):
def __init__(self, **kwargs):
self.txt0 = StringProperty()
class SomeApp(App):
def build(self):
grid = GridLayout(cols=1, size_hint_x=None, width="600dp")
self.lbl0 = Label(text='Tap and type a word/phrase below') # create a label instance
grid.add_widget(self.lbl0) # physically add the label onto the layout
self.txt1 = TextInput(text='', multiline=False) # create a text input instance
grid.add_widget(self.txt1) # physically add the text input onto the layout
btn1 = Button(text='Press') # create a button instance
btn1.bind(on_press=self.displayFunc) # binding the button with the function below
grid.add_widget(btn1)
# Add scrolling text
"""self.lbl1 = Label(text='Display') # create a label instance
grid.add_widget(self.lbl1) # physically add the label onto the layout"""
scrollWidget = ScrolllabelLabel(text=self.lbl1.text)
grid.add_widget(scrollWidget)
return grid
def displayFunc(self, userInput):
self.lbl1.text = self.txt1
SomeApp().run()
Ich habe diesen Fehler:
AttributeError: 'SomeApp' object has no attribute 'lbl1'
'self.lbl1.text = self.txt1' bearbeiten scrollwidget, das ist dein Attribut Fehler und verwenden self.txt1._text_, weil Sie Texteigenschaft wollen, nicht das Widget selbst. – KeyWeeUsr
Wie führe ich Ihren Vorschlag von "self.lbl1.text = self.txt1 edit to scrollwidget" durch? – KubiK888
